PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 308,786, dated December2, 1884-.

- Application filed May .24, 1884. (Mode-l.)

T at whom it may concern:

Be it known that I, VVILLIAM S. MoRRIsoN, of Fort WVorth, in the countyof Tarrant and State of Texas, have invented a new and ImprovedPiperench, of which the following isa full, clear, and exactdescription.

This invention consists of a pipe-wrench comprising a bar having ahook-ended arm pivotally connected to said bar, and certain details inthe construction of said parts, sub stantially as hereinafter more fullyset forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

1 in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a side elevation of the pipewrench. Fig. 2 is an endelevation of the same, and Fig. 3 shows the bar as used for extra'ctingspikes.

A is the handle-bar of the wrenclnhaving a foot, a, of curved form, andslotted to receive the arm. B is the arm held in the slot of the bar bya pivot-pin, b, that is held by a springcatch, 0, which allows readyremoval of the pin. The arm B has both ends formed hookshaped'0ne beinglarger than the otherand is made with three or more holes for thepivotpin, so that'the end in use can be set nearer to and farther fromthe serrated end of the foot a. The arm is to be reversed end for end,

according to the size of pipe, and this doubleended arm,with its endwiseadjustment, adapts the wrench for a large range of work. The

3 5 tool always relieves itself from the pipe as soon as pressure isslackened.

Pipe-fitters usually need to carry separate chisel-bars andnail-drawers. I save the extra weigh t and expense by forming the outerend, (I, of the bar A tapered, so as to serve as a chisel-bar, or 'as ascrew-driver with a small wrench, and the curved end of the foot a ismade with a notch, 6, 'so that the bar can be used for drawing spikesand nails. The manner of using the bar as an extractor is shown in Fig.3, and it is to be observed that the curve of the foot forms a rollingfulcrum that gives the greatest leverage in startingthe nail and a morerapid movement after the nail is started.

Having thus described myinvention, Iclaim as new and desire to secure byLetters Patent- 1. In a pipe-wrench, the bar or lever, in combinationwith the pivoted arm having reversely-hooked ends, one of said hookedends having a greater curvature than the other said hooked end,substantially as and for the purpose set forth.

2. In a pipe-wrench, the bar or lever having a lower curved and serratedend, in combination with the pivoted arm having reversely-hooked ends,one of said curved ends having a greater curvature than the other saidhooked end, substantially as and for the purpose set forth.
